Right below the dam by the fish hatchery is the best place, all you really need are scuds, sow bugs, San Juan worms, sculpin patterns, and wooly buggers. I'd like to add that a small light sink tip on a dark wooly bugger can be deadly some days when the water isn't running, especially in the area by the boat ramp, did that one year and the sink tip made the difference. Any other time I'm stripping big sculpin patterns for the Browns and bigger bows, or dead drifting scuds(tan,green,and Grey are best) under a red, tan, pink, or orange San Juan worm (or shamois worm). 4-5x fluorocarbon is key up there, VERY clear water. If you're looking for flies for there too shoot me a pm.
